LOG TRANSFERRING DEVICE Filed July 24, 1929 l cured to the alternate link of the chains 21 alternately one with the other, the plates being provided with `right angular flanges 25X extending from the lower Vedge of the plate so as to form Athe plate 25 into a troughfor conveying the logs 26 as indicated by dotted lines in Fig. 1. i

inclined upper end 26X and an opening 26vv for permitting the passage of the flanged n portions 25X of the plates 25. 27 isfafbumper plate which is secured to the side bars 12 directly opposite the drum-4 and against which the logs impact as they are dischargedy on to theconveyor bythe drum 4:. Y

` Having described the particular parts involvedinmy invention I will briefly describe the operationof the same. l 1

The logs are placed upon the conveyor 1 at their source of supply in a position extending longitudinally of the conveyor. rIn this way they are fed forward to the drum l1, The drum 4 revolving at a high speed grips the log as it isreceived by its frictional sur-v faceand impels it forward so as to throw it longitudinally over the trough conveyor until its forward end strikes the bumper plate 26X. The log then drops onto/the troughfconveyor so as to enter one of thetroughs formedby the plate 25 and'flange 25X, the log being engaged by said flange so as tol align ittra'nsversely. The end portions of the logs as they *are carried up by t-he trough conveyor bear upon the bearing plates 14 and 15 as clearly indicated in Fig. 1 so-that the major portion .of the weight is relieved from the conveyor.. The flanges 25X engaging the logs draw the logs upwards untilthey reach'the upper endl of the conveyor. The outwardly inclined portions 14X of the plates ,14 and 1,5

and over which the lends ,of the logsA travel drawl the Vlogs yout of engagementwiththe flanges25" carrying them clear of the trough` conveyor so that they discharge freely onto a pile or receptacle'into which they are fed.

By means of thisl construction the friction fin theA trough conveyor is'reduced toa mini-V mum 'sok that'the logs travelk upward continuously and evenly. Y rAlsoby meansr ofthe disi charging drum-1 thedirection of travel of the logs is altered without changing their po.- sit-ion and therefore there kis no danger of their becoming tangled at the point where they change directionand thereby clogging the apparatus.

It'inay also be pointed out that by reason of thedrum `21revolving at ahigh speedin` Vrelation to the conveyor 1 when two logs are travelling longitudinally upon the conveyor 1, one log being slightly ahead of the other, the log ahead is first gripped by the drum andis shot for-ward onto the trough conveyor'thereby separating it from its followv ing log so that practically all the logs are at right angles one with theother fromthe` point of feed. to thefpoint of discharge withoutv any danger of the logs tangling or crisscrossing. ty will be readily understood that where two ordinary conveyors are employed one extending at right angles to the other, that as .the logs are fed from one conveyor onto the other, they are more or less piled one on top ofthe other in all positions at the point of change of direction of the logs travel and thereby prevent any easy feeding of the mechanism, discharging them in a. confused mass, increasingthe power necessary to drive the conveyor and preventingany possibility of their being piled evenly when'discharged from the discharging point; lhat IV claim as my invention is :f-

-'1. :[nV` a. log transferring device, the combination with a 'main conveyor extending from aV source of log supply and upon which logs are fed longitudinally, an upwardly inclined troughed conveyor extending at right angles to the main'conveyor, and means for automatically engaging each log as it is dischargY edV from the main conveyor and impelling it forward longitudinally at a speed greater than kthat of the main conveyor to drop into the troughs of the troughed conveyor.'
